It's interesting for Cassini passing so close to Saturn that it is able to see the hazy, blurry edge of Saturn's atmosphere. One wonders how much of the glow extending beyond the blue part is a camera effect and how much is actually tenuous upper atmosphere. I'm under the impression that Saturn's mass creates a strong gravity that doesn't allow for such a huge extension so I suppose it's mostly the camera.

Argimusco - The Old Rocky Man
www.dariogiannobile.com
Copyright: Dario Giannobile Between the Mediterranean sea and the volcano Etna, the upland of Argimusco stands towards the sky. An impressive and evocative place where different monoliths emerge from the ground. Recent studies demonstrated that the site has been used as a natural calendar in order to measure the seasons' cycle. In the next coming years the Argimusco could become the Mediterranean Stonehenge. Different shapes characterize the monoliths like this old rocky man looking at the sky. Some think that the monoliths have been shaped by wind and rain, other that they are man-made in order to represent the constellations on earth as in this case: Ofiuco.

KeyHole Nebula in Hubble Palette

One of most energetic and enigmatic galaxies in the whole sky, whose history is likely very dramatic, involving galaxy cannibalisation and the formation of a huge super massive black hole

Object/Date:
C/2014 Q2 (Lovejoy) @ 2015-05-23
Tech data:
Takahashi FSQ 106mm f/5 refractor + SBIG STL-1100M camera (L:3×300 Bin1 + RGB:1x60 Bin2)

Description:
Comet C/2014 (Lovejoy) imaged on May 23, 2015 when was at 2.5 deg from Polaris and above the IFN background (Integrated Flux Nebulosity). In spite of the comet has moved away until more than 2 A.U. from the Sun and Earth descending to 8 magnitude, still shows a ionic tail of 45' longitude toward northwest, and a short anti-tail toward east.

Location:
Remotely from Mayhill, New Mexico (USA)

The dome guards a +100 years old 9 meter focal lenght refractor telescope.

The landscape was just amazing, our Galaxy, Milkyway was passing just above the cypresses of the forest of Liapades at Palaiokastritsas bay.
The Lagoon nebula also know as M8 was just at the edge of the hill passing behind the big cypresses, just like hide and seek was appear and disappear.
In this picture expect M8 you can also see M20-M21,M16-M17, M23, M25 also Messier-24 the Sagittarius Star Cloud approximately 600 light years wide.
